The Lowdown
Alright, Rusty here. Let’s talk Karramarro in feet and miles per hour.
This spot is an advanced point break that only really works when the swell comes from the northwest. It’s inconsistent, so you’ve gotta be willing to wait for it. Water temp is about normal for this time of year, nothing to worry about.
The first few days are a bit of a letdown. Monday morning the 7th has a glassy 3ft swell from the northwest with a 9-second period. The combined energy is weak (306), so it’s small but clean. That’s the best for a while. Monday afternoon turns cross-on and bumpy, and Tuesday the 8th through Thursday the 10th is mostly choppy or marginal. Thursday morning the 10th has a bit of offshore wind and 4ft from the northwest, but it’s only so-so.
Friday the 11th and Saturday the 12th are flat. Swell drops to 2ft or less, energy under 100. Don’t bother.
Now Sunday the 13th is our first real standout. Glassy morning, 4ft from the northwest, but the period jumps to 13 seconds – that’s a nice long groundswell. Energy hits 606, so there’s some power behind it. The long period will draw some nice lines down the point, but expect longer waits between sets. Crowds are likely, so get in early.
Monday the 14th keeps the quality. Another glassy start, 5ft from the northwest with a 12-second period and energy at 666. That’s a solid session. The size is starting to push into the expert zone, so be careful if you’re not confident.
Tuesday the 15th and Wednesday the 16th are messy with onshore winds, even though the swell is still 6ft on Wednesday morning. Choppy and not worth it.
Then from Thursday the 17th through Saturday the 19th, we get a beautiful run of glassy mornings. Thursday has 5ft (energy 484), Friday has 5ft (energy 456), and Saturday holds 5ft to 5ft with glass all day. The period is a shorter 10 seconds, so it’s a bit more user-friendly, but still clean and consistent. This is the best stretch of the outlook. Crowds are likely, and for good reason.
Sunday the 20th and Monday the 21st fade out. Swell drops to 4ft or less, and the wind is either offshore or cross-on but small. Not much to get excited about.
So, your best bets are Sunday the 13th and Monday the 14th for the longer period, and then the whole run from Thursday the 17th to Saturday the 19th for the cleanest, most consistent waves. That’s where you wanna be.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
